A document has leaked from Staples, the office supply store, that lists an Amazon Card Reader as a new product landing at the retail store next month. An Amazon Card Reader suggests that the ecommerce giant is getting a new mobile credit card processing platform.

Along with the Amazon Card Reader, the documents also show that Staples will start to sell a PayPal Here Mobile Card Reader and its own branded card reader. Documents suggest that the Amazon Card Reader will sell for $9.99 and it is expected to connect to a smartphone for processing.

Speculation is that the Amazon Card Reader might connect with the recently unveiled Amazon Wallet App that launched last week. Related rumors suggest that Amazon is working on other payment hardware including fingerprint scanners and more.
